Since the signature was made necessary by the ambiguity on which type
of exception you wished to catch with your "try", using (SomeException
_) in your pattern match should make that clear. By the way, why are
you show()ing a String ? The only thing that does is adding quotes
around it and escaping some characters, shouldn't you just use :

>        Left (SomeException _) -> jsonToRepJson $ object ["response" .= "ERROR: NO DATA FOR ONE REASON OR ANOTHER"]
